Wasserstoff im Gasnetz

The energy transition and the legally enshrined path to climate neutrality mean that the use of fossil natural gas must be significantly reduced in the long term. At the same time, hydrogen is becoming increasingly important in the gas network as a central component of a climate-neutral energy system. Green hydrogen, biomethane, and synthetic gases make it possible to continue using existing gas infrastructures while sustainably reducing CO₂ emissions.

For many existing gas networks, the question of sustainable use therefore arises. In regions with declining natural gas demand, gradual decommissioning may make economic sense. In other areas, converting gas networks to hydrogen or feeding hydrogen into existing gas networks (blending) offers a strategic option for preserving infrastructure value and supporting the transition to a climate-neutral energy supply. The integration of green gases and the development of CO₂ transport networks are also gaining relevance in the course of the transformation.

The central challenge in introducing the switch from gas to hydrogen lies in the technically, economically, and temporally coordinated implementation. Networks must be operated safely, investments must be managed efficiently, and transformation paths must be designed in a socially acceptable manner. Only through integrated planning can decommissioning, repurposing, and new construction be optimally coordinated.

AIT specializes in transforming gas networks into hydrogen networks and climate-neutral infrastructures. Together with network operators, energy suppliers, and local authorities, we develop sound gas network transformation plans, analyze hydrogen feed-in scenarios, accompany the transition to H₂ operation, and support the development of hydrogen transport networks. In addition, we integrate biomethane, synthetic methane, and CO₂ networks into holistic energy system solutions.

• Strategic gas network decommissioning scenarios and repurposing concepts
• Transformation plans for gas and hydrogen networks in the integrated energy system
• Hydrogen blending and conversion to pure H₂ operation
• Planning and design of hydrogen transport networks
• Integration of green gases and CO₂ infrastructures

With our systemic analyses, energy system models, and economic assessments, we create the basis for decision-making for the safe, economical, and sustainable use of hydrogen in the gas network.
